Place slices of meat next to each other on the work surface, season with salt and pepper. Place one slice of mozzarella and 2 basil leaves on each half of the fillet slices. Place the remaining slices of fillet on top of each other to form a small packet as a lid. Wrap a slice of ham around each package (be careful: ham must not tear).
Heat the oil in a large frying pan and fry the parcels very slowly over a low to medium heat for 10-12 minutes while turning. In the meantime heat milk and butter.

Fold the herb crème fraîche into the puree with a fork so that it is marbled
